For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.

[0036] Embodiment 1:

[0037] AsFigure 1-6 As shown in the figure, the present invention provides a device for drawing quartz fiber using a quartz glass rod, including a furnace body 1. A cavity 2 is provided inside the furnace body 1. A fixing mechanism for fixing a molten pool 3 is provided in the cavity 2. A plurality of diversion nozzles are provided at the bottom of the molten pool 3. A heating mechanism, a cooling mechanism and a sprayer 4 are provided on one side of the molten pool 3 in the cavity 2. A bundling groove 5 and a wire drawing machine 6 are provided in the cavity 2. A rotatably connected bracket 7 is provided on the furnace body 1. A first motor 8 for driving the rotation of the bracket 7 is provided in the furnace body 1. Clamping mechanisms for fixing a product 9 are symmetrically provided on the bracket 7. A through groove 10 matching the product 9 is provided in the cavity 2 above the molten pool 3. A rotatably connected baffle 11 is provided on the furnace body 1 on one side of the through groove 10.

[0038] Specifically, before the work starts, the molten pool 3 is fixed by a fixing mechanism, and each of the two clamping mechanisms fixes a product 9. When the work starts, the heating mechanism starts working first to heat the molten pool 3. When the molten pool 3 reaches the first preset temperature, the clamping mechanism starts working, driving the product 9 to move downward. The product 9 enters the interior of the cavity 2 along the through groove 10. As the movement progresses, the product 9 moves into the molten pool 3 and softens and melts into a molten slurry state, and uniformly drips along a plurality of flow nozzles. At this time, the heating mechanism controls the temperature of the molten pool 3 to be the second preset temperature, and then the cooling mechanism starts working to cool the product 9 dripping from the flow nozzles. The operator guides the wire through the sprayer 4, and the sprayer 4 coats the sizing agent on the surface of the cooled product 9. Then the product 9 converges in the bundling groove 5 for bundling. Finally, the operator winds the bundled and stranded product 9 onto the wire drawing machine 6 for wire drawing operation. When the clamping mechanism drives the product 9 to move downward to the limit, it indicates that the processing work of this round of product 9 is completed. At this time, the heating mechanism, the cooling mechanism, and the sprayer 4 stop working, and the clamping mechanism drives the product 9 to return to its original position. The rotating baffle 11 blocks the through groove 10. At this time, the baffle 11 cooperates with the furnace body 1 to store the residual heat in the molten pool 3. At this time, the first motor 8 works to drive the bracket 7 to rotate, thereby driving another product 9 to move above the through groove 10. At this time, the rotating baffle 11 is rotated, and the baffle 11 no longer blocks the through groove 10, and the clamping mechanism drives the product 9 to continue the processing work; Optionally, the temperature of the molten pool 3 is detected by a far-infrared temperature measuring device; Optionally, the first preset temperature is 2000~2200 °C, the second preset temperature is 1800~2000 °C, and the speed at which the clamping mechanism drives the product 9 to move downward is 0.25~1.25 mm / min; Optionally, the diameter of the product 9 is 200 mm, the length is 2000 mm, and the roundness is less than 20 μm; The bottom of the product 9 is conical. When the bottom of the product 9 moves into the molten pool 3, it is convenient to accelerate the melting process of the product 9 and make the melting of the product 9 uniform; Optionally, the molten pool 3 is made of a graphite crucible coated with an antioxidant coating, or a high-temperature resistant ceramic crucible such as a silicon nitride crucible, a silicon carbide crucible, a boron nitride crucible, an alumina crucible, or a zirconia crucible; The wire drawing machine 6 is a glass fiber wire drawing machine.

[0039] The present invention cooperates with a clamping mechanism, a furnace body 1, a bracket 7 and a baffle 11. Compared with the existing wire drawing method of melting multiple quartz glass thin rods by gas flame, the present invention melts the same larger product 9 and cooperates with multiple guide nozzles on the molten pool 3 to complete the wire drawing work. The work efficiency is high and the wire drawing work is stable. When one product 9 is completed, the furnace body 1 cooperates with the baffle 11 to store the residual heat of the molten pool 3 so as to quickly heat the molten pool 3 to the required temperature, and then the product 9 is quickly replaced by the bracket 7, so that the device can continuously perform the wire drawing work. At the same time, the heat during the work is stored and utilized, thereby ensuring the working effect and economy of the device.

[0040] In one embodiment, the clamping mechanism includes a top plate 12 arranged on the bracket 7, the bracket 7 is provided with a sliding plate 13 slidably connected below the top plate 12, the top plate 12 is provided with a cylinder 14 for driving the sliding plate 13 to move, the sliding plate 13 is symmetrically provided with a sliding arc plate 15, the sliding plate 13 is provided with a fixed block 16 on one side of the arc plate 15, a bolt is rotatably connected in the fixed block 16, one end of the bolt is rotatably connected to the arc plate 15, the two arc plates 15 cooperate to clamp the product 9, and the sliding plate 13 is provided with a groove 17 matching the product 9.

[0041] Specifically, when it is necessary to clamp the product 9, the product 9 is placed on the inner side of the two arc plates 15, and the top of the product 9 is placed on the inner side of the groove 17. The groove 17 serves as a limit for the product 9. The two bolts are rotated to drive the two arc plates 15 to approach each other, so as to clamp the two sides of the product 9. The two arc plates 15 cooperate with the groove 17 to stably clamp the product 9, and the groove 17 and the molten pool 3 are located on the same axis to ensure that the position of the product 9 is aligned with the molten pool 3, thereby ensuring the stability of the device during operation. After the product 9 is fixed, the cylinder 14 on the top plate 12 starts to work, driving the slide plate 13 to move downward, and the product 9 moves downward accordingly, so that the product 9 is processed.

[0042] In one embodiment, the fixing mechanism includes a support plate 18 slidably arranged in the cavity 2, and a base 19 matching the molten pool 3 is provided at one end of the support plate 18. A driving mechanism for driving the support plate 18 to move is provided in the cavity 2. When working, the molten pool 3 is placed on the inner side of the base 19. The base 19 fixes the molten pool 3, and when the molten pool 3 needs to be replaced, the support plate 18 can be driven downward by the driving mechanism, so that the base 19 and the molten pool 3 move to the bottom of the heating mechanism, so that the molten pool 3 can be taken out of the base 19 for replacement.

[0043] An embodiment, the cooling mechanism includes an annular block 29 disposed inside the cavity 2. A plurality of spray nozzles 30 are evenly arranged inside the annular block 29. An air blower is provided on one side of the bottom of the base 19 away from the support plate 18, and an air suction fan is provided on one side of the bottom of the base 19 close to the support plate 18. A water absorbent cotton 20 is provided at the bottom of the support plate 18.

[0044] Specifically, when the cooling mechanism works, cooling water is sprayed out from the spray nozzles 30 on the annular block 29, so as to cool the product 9 dripping from the molten pool 3. When part of the cooling water contacts the product 9 and evaporates to generate water mist, it is likely to affect the operation of other mechanisms. By controlling the air blower to work, the air blower is located above the cooling mechanism, and the air blown out by the air blower blows the upward moving water mist to one side of the air suction fan. The air suction fan blows the air containing water mist to the water absorbent cotton 20, so as to absorb part of the water mist and reduce the influence of the water mist on other mechanisms, ensuring the use effect of the device.

[0045] An embodiment, the heating mechanism includes a plurality of connecting rods 21 disposed at the top of the inner wall of the cavity 2. One end of the plurality of connecting rods 21 is rotatably connected to the same ring 22. A plurality of blowtorches 23 are evenly arranged inside the ring 22. The blowtorches 23 face the molten pool 3. A first gear 24 is sleeved on the outer wall of the ring 22. A rotating rod 25 is rotatably connected on one side of the first gear 24 inside the cavity 2. A second gear 26 is sleeved on the outer wall of the rotating rod 25. The first gear 24 meshes with the second gear 26. A second motor for driving the rotating rod 25 to rotate is provided inside the furnace body 1.

[0046] During use, the connecting rods 21 support the ring 22. When it is necessary to heat the molten pool 3, a plurality of blowtorches 23 start to work. The blowtorches 23 face the molten pool 3 to heat the molten pool 3. The second motor starts to work, driving the rotating rod 25 to rotate. The rotating rod 25 drives the second gear 26 to rotate, thereby driving the first gear 24 to rotate. The ring 22 rotates with the first gear 24, driving the blowtorches 23 to rotate around the molten pool 3, so that the blowtorches 23 heat the molten pool 3 evenly, ensuring the working effect of the device; Optionally, the blowtorch 23 is one or more of a quartz blowtorch, a copper blowtorch, an aluminum alloy blowtorch, and a stainless steel blowtorch. The fuel gas used by the blowtorch 23 is one or more of hydrogen, methane, ethane, and propane.

[0047] An embodiment, one end of the rotating rod 25 extends below the fixing mechanism and is sleeved with a reciprocating lead screw 27. A pressing block 28 is threadedly connected to the reciprocating lead screw 27, and the pressing block 28 is slidably connected to the inner wall of the cavity 2. When the second motor drives the rotating rod 25 to rotate, the rotating rod 25 drives the reciprocating lead screw 27 to rotate, thereby driving the pressing block 28 to perform reciprocating up and down motion. The pressing block 28 can squeeze the water-absorbing cotton 20 to avoid excessive water absorption on the water-absorbing cotton 20 and ensure its water absorption effect. When the driving mechanism drives the support plate 18 to move downward, rotate the reciprocating lead screw 27 so that the pressing block 28 is at the bottom of the reciprocating lead screw 27 to prevent it from affecting the movement of the support plate 18.

[0048] Embodiment Two:

[0050] Place the melting pool 3 on the fixing mechanism for fixation, and fix the product 9 through the clamping mechanism;

[0051] Heat the melting pool 3 through the heating mechanism. After the melting pool 3 reaches the first preset temperature, the clamping mechanism drives the product 9 to slowly descend;

[0052] After the product 9 enters the melting pool 3, melts and drips through the flow guiding nozzle, adjust the heating mechanism to control the temperature of the melting pool 3 to the second preset temperature, and start the cooling mechanism;
